JOSEPH M. GEISINGER, OF WARSAWV, INDIANA.

WELL-BORING MACHINE.

SPECIFIGATION forming part of Letters Patent No. 565,343, dated August 4, 1896.

Application filed March 23, 1896. Serial No. 584,581. (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH M. GEIsINeER, a citizen of the United States, residing at WVarsaw, in the county of Kosciusko and State of Indiana,have invented a new and useful Well- -mechanism illustrated in the accompanying drawings, in which- Figure 1 is a rear elevation of the machine with the hammer removed. Fig. 2 is an end elevation. Fig. 3 shows rear elevation of the hammer with the removable cushion in place. Fig. 4 shows side elevation of the hammer and of the cushion removed. Fig. 5 is a plan of hammer.

Similar letters refer to similar parts throughout the several views.

A is the driving-pulley on main shaft.

B is a friction-pulley on main shaft connecting, by friction-pulley D on lever P, with friction-pulley G for hoisting drill or drivepipe N and hammer L by means of rope T, wound on drum J.

E is a bevel-pinion on main shaft connecting with bevel-pinion F on spline-shaft O.

H is a gear on drill or drive-pipe N, keyed thereto by corrugated corner-wedges I to effeet the rotary motion in drilling or boring by its engagement with the pinion G, mov-' able on the said spline-shaft.

K is the removable wooden cushion-block used in hammer L when driving drill or pipe, and removable when rope T is used for raising or lowering drill or pipe.

M M are sheaves at top of derrick for carrying rope T.

P is the lever to operate friction-pulley D, conveying power from drive-pulley A to friction-pulley C on end of drum.

Q is lever for throwing the rotary mechanism in or out of gear.

S is the derrick, which I propose to make in four sizes, from ten to fifty feet in height, with proportionate base R.

U is the main shaft, and will extend through pinion E far enough to put on pitman-wheel for pumping. (Not shown in drawings.)

What I claim, and desire to secure by Letters Patent, is

1. The combination with a derrick-frame, the drill or drive-pipe having bearings therein, and the gear on said drill or drive-pipe, of the spline-shaft 0 parallel with said drill or drivepipe and carrying gear which is adapted to mesh with the gear on the drill or drive-pipe, means for actuating said shaft 0, means whereby it may be thrown out of gear with the driving mechanism, a hammer arranged to reciprocate in the derrick above the end of the drill or pipe, and having a longitudinal opening therethrough a removable cushionblock for said hammer, an operating-cable designed to be connected either to said hammer, or to the drill or drive-pipe, and means for winding the same, substantially as specified.

2. The combination with the derrick-frame, the drill or drive-pipe having bearings therein and the gear-wheel carried thereby, of the spline-shaft O, the pinion thereon adapted to mesh with the gear on the drill or drive-pipe, the main shaft journaled in the base of said frame, and having a friction-pulley, gear connections between the said main shaft and the spline-shaft, means for throwing said gear out of operation, the hammer arranged to reciprocate in the upper portion of said frame and having a vertical opening therethrough, the removable cushion-block therefor, the operating-cable adapted to be connected either to said hammer or to the drill or drive-pipe, a winding-drum for said cable, a friction-pulley on the shaft of said drum, a lever pivoted to the frame, and a friction-wheel carried by said lever and adapted to be connected with the friction-pulleys on the main and drum shafts, substantially as specified.

3. The combination with the frame, the main driving-shaft j ournaled in the base thereof, the friction-pulley thereon, the drill or drive-shaft, gear connections between the same and the main shaft, and means for throwing said drill or driveshaft out of gear, of the hammer arranged to reciprocate in the upper portion of said frame, and having an opening therethrough, the cushion block adapted to be removably secured in said opening, the operatingcable, its Winding-drum, the friction-pulley O on the drum-shaft, the lever P, and the friction-wheel carried by said lever all substantially as and for the purposes described.

4:. The combination with the frame, the drill or drive-pipe j ourn aled therein, the gear- Wheel carried thereby, the adjacent splineshaft 0, its gear-Wheel or pinion G, and means
